eac3to - audio conversion tool

[BlackJack1]

One simple question:
how you put long filenames and strings in CMD window? what is the smartest way to do it?

Maybe I'll add support for that in a future version if it's really needed. For now you can use either mkvmerge or you could try removing the first few milliseconds of the TS file. That should make it work with eac3to, too.

can anyone recommend a good and reliable mpeg2 .ts cutter for this? I only know h264ts_cutter which doesnt work for mpeg2 files.

No, it means 24/1.001 = 23,976023976023976023976023976024.

LOL. Are you sure about the number of decimals?

[Thunderbolt8]

go to 'calc' and type 24 / 1.001 and see whats the result

Just drag them from the folder to the cmd line.

Thank you
It works...

I am speechless!!
MKVtoolnix with DTS-HD support!

Aha, that result is wrong. In fact 24/1.001 is a recurring fraction with a period of 6 digits. To be precise the digits 023976. So to implement 24/1.001 in eac3to is not the trivial task it appears to be at first sight .

[BlackJack1]

Yeah... it works..... but:

Please advice.

Surcode doesn't like long filenames/paths. Change them and you 'll be ok (assuming -test is working).

are you sure that Enron is 24p?
The raw avc stream played pack with libav or coreavc is reported as 29.97fps
Also the mkv created with eac3to (with -24p switch) is reported as 29.97fps

I'm using TsSplitter. It's a fairly simple tool with no preview. It can just split a TS file into multiple parts. I'm usually cutting a big TS file into 128MB pieces. Then I'm cutting the first piece into 8MB pieces. You can go as low as you want. Finally you can simply delete the first few pieces. In order to put everything back up together you can select all files in the Explorer and drag them to the TsSplitter screen. Press "sort", then "join" and you'll have your one big TS file back.

Another alternative would be to use a hexeditor to cut some bytes from the beginning of the stream. For TS files use a multiply of 188 bytes. E.g. try removing ca. 1MB. Maybe that fixes the problem.

I believe VideoRedo can also do the cutting directly.

Delete the gaps file and the mkv and do it again - but this time using the "-24p" switch.

Surcode doesn't like too long filenames. Make them shorter, then it will probably work.

No, I think it's rather 48i...

See? The Sonic HD Demuxer (which was probably used by your raw stream playing graph) is confused in the same way as eac3to is. Both see this movie as being 29.97fps. But actually the movie is playing too fast when muxed this way.

Just compare the runtime of the demuxed audio streams to the muxed MKV runtime. You'll see that with 29.97fps muxing the video runtime is much shorter than the audio runtime. With 23.976fps video and audio runtime match.

This might be a bug. What does mkvinfo say? It should say 23.976. If it doesn't then it is a bug.

[Thunderbolt8]

I also thought of tssplitter first, but since it apparently can only split in even parts ill have to split the first part multiple times again, like you said, which I actually would like to avoid because somehow I dont trust all that splitting and rejoining not that much. but I guess it works flawlessly, there isnt anything like funny timestamps which could occur at the split or join points or other problems like with .m2ts files (e.g. sync problems etc)?

mkvinfo:
"default duration: 33.367ms (29.970 fps for a video track) at 4457"


But you are correct. It does play at the correct speed (23.976fps).

TsSplitter is really "stupid" in a good way. It cuts and joins without the slightest changes to the data. You can even join e.g. PCM audio tracks with TsSplitter...

Don't worry about timestamps. There's nothing that can brake. Of course you should make a copy of the original file, just in case something goes (unexpectedly) wrong. E.g. you can mess things up if you forget to press the "sort" button!

Ok, that's an eac3to bug.

[Jaja1]

Enron works fine now with -24p. Great.

Just tried Jimi Hendrix at Monterey. Evodemux reports 24/1.001, whereas the mkv made with eac3to is 29,970 fps according to mkvinfo.

[madshi]

Live concerts are usually natively interlaced (29.97) so I think eac3to is behaving correctly. FWIW, I believe EvoDemux always shows 24/1.001, no matter whether video is really 24/1.001 or 30/1.001. I don't think EvoDemux' framerate detection is working correctly.

[Jaja1]

Hendrix is shot at film, why use anything else but 24fps for the conversion to video
